Possible whitelist feature suggestion

2008-09-24 by Seth Mos

Hi,

I just thought of the following feature for milter-greylist, since 
milter-greylist is already familiar with all smtp communications and can 
keep statistics regarding the amount of email blacklisted, whitelisted, 
greylisted and delay times.

What I would ideally like to have is a smtp server whitelist which is 
determined based on a minimum number of accepted messages from this server.

Something along these lines.

/* Servers that sent over 500 accepted emails are whitelisted */
list "clean server" okaddr 500
acl whitelist list "clean server"

Here is a example for a suggestion I made quite a while ago. It also is 
directed mainly for whitelist email servers.
/* Servers that match the MX record for the sender domain are 
whitelisted which match the subnetmask bits */
/* example matches all hosts within a /24 subnet */
list "clean mxrecord" mxaddr 24
acl whitelist list "clean mxrecord"

Perhaps a rrd data collector backend would prove very useful for insight 
into the milter-greylist operation.

What I have now is a combination of shell scripts which grep through the 
log files and then proceed to update the RRD databases with the 
different results.

I can ofcourse also make these scripts available on my website if anyone 
is interested. But a more integrated approach for a RRD data collector 
would definitely be something nice to have.

What I have now looks something like this.

Interestingly it also shows that my backup MX receives almost no email 
at all.

Kind regards,

Seth Mos
